Creating a safe, effective learning environment is a key priority at Mater Dei. Positive student behaviour is encouraged and affirmed, student safety is ensured and risks minimised by working within a Catholic framework that emphasises the dignity of each person, values restorative justice and encourages students to take responsibility for their actions and words. Mater Dei operates within Diocesan guidelines and policies regarding the management of student behaviour through the adoption of a Whole-School Positive Behaviour Support model. House Leaders and KLA Leaders work together to ensure that learning and wellbeing are a collective priority.
